Ive downloaded this and in the folder "east" theres 2 readme files in german and i dont understand it.

hes talking about wtd and wtr files and something about bronx_e.img einfügen, einfugen i take it means insert or merge idk. and the readme file 2 its wtd and wtr "brook_s2.img" einfügen. This file isnt in his modfiles but i find it in gta4 when i use openiv. Ill paste the readme file and hoping someone could help me explain what he really means cause the way i see it its not enough to just paste his folders into gta4 without doing this first.
